Today only: Every book on Amazon is 25% off by Kim Komando

Amazon's most recent deals haven't been too kind to the folks out there who just can't handle e-books. Until today, most of the sales involved Amazon's Kindle e-reader or digital copies of novels.
That ends today.

You can get 25% off any one book by entering the promo code BOOKDEAL25 at checkout.
And when I say any book, I really mean any book. Watch out, because you're only allowed to get print copies of books. No digital editions. Also, this deal only works for one book. Choose wisely.
While you're at it, you might also want to check out Amazon's 12 days of deals. The site highlights different types of products every day. Today's, for example, is for people with active lifestyles.
